Ring-Cleavage Products Produced during the Initial Phase of Oxidative Treatment of Alkyl-Substituted Aromatic Compounds.

ABSTRACT: Chemical oxidation with hydroxyl radical (HO^•) and sulfate radical (SO₄^•-) is often used to treat water contaminated with aromatic compounds. Although oxidation of aromatics by these radicals has been studied for decades, the commonly accepted transformation pathway-sequential hydroxylation of the ring followed by ring cleavage and mineralization of the resulting products-does not account for the loss of the parent compound observed during the initial phase of the process. To assess the importance of pathways for aromatic compound oxidation that do not result in ring hydroxylation, we identified products formed after the initial reaction between HO^• or SO₄^•- and benzene, toluene, ethylbenzene, and (BTEX) xylene isomers.
